Technology is advancing and new products are put into use. Whether it pulls through the market or not, it’s remarkable to try something different. At the recent industry power show, Infineon announced the latest GaN material application, a 65W USB PD charger. This charger uses the third-generation semiconductor material, Gallium Nitride (GaN) which was developed by Infineon and is called “CoolGaN”.
This new Infineon product supports an output of 5-20V. The AC 90V has a full-load output efficiency of 93% and a unit power density of up to 20W per square foot. This helps to miniaturize and trim down the high-power power supplies.
Gallium Nitride has a wide range of applications, including semiconductor lighting, lasers, and RF. It can be used in power supply products to achieve high power output in ultra-small volume. Prior to this, Anker, a Chinese company had released the world’s first charger with GaN, which is small in size but has an output of 27W. At present, there are more and many fast charging devices for GaN materials, and it is getting closer to large-scale commercial use.
